ROPT-20-1
Purpose
The relay ROPT-20-1 with microprocessor management is intended for restriction of starting current by means of the extinguishing resistors at connection of inductive or capacitor loading to a single-phase network of 220 V, 50 Hz.
Design of system
– The ROPT-20-1 relay is executed in the case for installation on a DIN lath.
– On the forward panel of the module there are indicators "NETWORK", "ACCIDENT".
– In the lower and top part of a product there are terminal blocks for connection of the relay to a network and to loading.
– Power supply of the relay is carried out directly from a controlled network. (Pict. 1)
